What is AUDIT ransomware? And how does it execute its attack?

AUDIT ransomware is one of the latest variants of Dharma ransomware that is released on November 2018. This new Dharma variant uses .AUDIT extension in marking the files it encrypts. Nothing much has changed in this new variant except for the extension it uses as well as its email address which is now payransom@qq.com. Although there are only minimal changes to this new variant, AUDIT ransomware still remains dangerous as other Dharma variants.

The instant its malicious payload is dropped in the system, it will connect the system to a remote Command and Control server operated by the attackers. It is where it downloads the rest of its malicious components and places them to system folders. From these components, a data gathering module will be employed which is used to obtain information from the infected system. Aside from that a stealth protection module is also employed that protects the crypto-malware from any security programs in the system that could interfere with the attack. It also modifies some registry entries in order to automatically run on every system startup. Following all these system modifications, AUDIT ransomware will begin encrypting its targeted files using a sophisticated encryption algorithm that were also used by other Dharma variants. After the encryption, the .AUDIT extension is added to every encrypted file. It then release a file named FILES ENCRYPTED.txt that contains the following message:

“all your data has been locked by us

You want to decrypt?

Write to email payransom@qq.com”

In addition, AUDIT ransomware also drops a file named Info.hta which contains the original ransom note of Dharma ransomware. It states:

“All your files have been encrypted!

All your files have been encrypted due to a security problem with your PC. If you want to restore them, write us to the e-mail

payransom@qq.com
